这里可能有什么问题?任何想法将不胜感激.
What could be the issue here? Any ideas would be greatly appreciated.
推荐答案
如果您的静态内容位于 /static、/public、 以外的目录中>/resources 或 /META-INF/resources.
If your static content is located in a directory other than /static, /public, /resources or /META-INF/resources.
然后将属性 spring.resources.static-locations 添加到您的 application.properties 以指向静态内容.
Then add property spring.resources.static-locations to your application.properties to point to the static content.
spring.resources.static-locations=classpath:/templates/
您将在控制台日志中看到以下消息:
You will see the following message in the console log:
Adding welcome page: class path resource [templates/index.html]
参考文档
默认情况下，Spring Boot 从名为的目录提供静态内容/static(或/public 或/resources 或/META-INF/resources)在类路径
By default, Spring Boot serves static content from a directory called /static (or /public or /resources or /META-INF/resources) in the classpath
您还可以使用spring.resources.static-locations 属性(替换默认值带有目录位置列表的值).
You can also customize the static resource locations by using the spring.resources.static-locations property (replacing the default values with a list of directory locations).
